A survey of California’s natural gas storage fields initiated by the Public Utilities Commission (PUC) revealed that La Goleta storage field had experienced 17 leaks, all above ground, all nonhazardous, and all since repaired. The survey came in response to the four-month leak at the Aliso Canyon storage facility that caused thousands of nearby Porter Ranch residents to evacuate for health reasons. The PUC determined there were 66 leaks found at Alisos Canyon.
